This is an update to my post on January 15th. I think we're going to need a bigger boat.
Bessie turned 8-months old on March 1st. Last night I managed to pick her up and get on the scale and she weighs 77.5 LBS. That means she has only gained about 10 pounds in the last two months, a drop from her previous weight/size gain of over 10 pounds each month prior to January.
Bess is getting bigger in size but not as heavier as before. She has also not been eating as regular and I think I will be taking her to the Vet next Monday to see why her appetite has slacked off.
